Abstract

In response to the problem of high cogging torque in Interior Permanent Magnet Synchronous Motors (IPMSM), this paper first conducted a theoretical analysis of cogging torque, and then established a finite element model of 8-pole 48-slot IPMSM. The influence of opening auxiliary slots on cogging torque in the motor stator and rotor was compared and analyzed. Finally, the output torque, air gap magnetic density, air gap magnetic density harmonics, and no-load back electromotive force harmonics before and after opening the auxiliary slot were compared and analyzed. The results show that opening auxiliary slots on the stator and rotor simultaneously can effectively reduce the cogging torque of the motor, while also improving other performance.
